    Abstract: In a method and a system for maintenance planning for a technical device, a status value is in each case used to characterize a state of a technical unit. A state of a higher-level unit which has a number of subunits each having associated status values is characterized by a common status value, which is calculated as a weighted sum of the status values of the number of subunits. The common status value is used for planning maintenance tasks on the device. In one preferred embodiment of the invention, a significance value is provided for the higher-level unit and is further-processed together with an associated common status value, preferably in a common visual display and/or a computer combination. In a further preferred embodiment of the invention, any change in the status values with time is determined, and is used to predict a future development of status values.

    Abstract: A system (1) for assisting a field operator, in particular a maintenance field operator, by a remote assistant (51) equipped with a viewer (50) comprises a first group of components configured to be connected to a support (10) wearable on the operator's head, including a first video camera (11), a local viewer (13) arranged to be watched by the operator, a first control unit (15) and a first wireless connection interface (19). The system also comprises a handpiece (20) providing a visual sensor (21) such as a video camera or a thermal imaging camera, a serial port (24) for connecting a peripheral device (30) such as an instrument or a sensor or a video source, a second control unit (25) and a second connection interface (26). The connection interfaces (15,25) are configured for mutually changing, locally or through a remote server (99) available through a data network (3), data streams (12,22,32) coming from the video camera (11), from the visual sensor (21) or from the peripheral device (30), respectively, intended to be displayed by the local viewer (13). Moreover, the connection interfaces are configured for exchanging the data streams with the assistants (51) remote viewer (50) through the remote server (99). The system (1) also comprises a scenario-switching device (80) for displaying a same data stream of interest (42) at the same time to the local viewer (13) and to the remote viewer (50), said data stream of interest selected among data streams (12,22,32) related to the scenarios (11′,21′) framed by the video camera (11) and by the visual sensor (21), respectively, and to the data obtained from the peripheral device (30).

    Abstract: Methods, systems and computing devices are provided for using a completed corrective action as evidence of a fault. The methods, systems and computing devices receive equipment status evidence and determine an equipment fault based on the equipment status evidence. The methods, systems and computing devices also create and rank a list of potential failure modes based at least in part on the determined equipment fault, recommend a corrective action to correct the equipment fault based at least in part on the ranking of the potential failure modes and receiving additional equipment status evidence indicating that the recommended corrective action failed to correct the equipment fault. The methods, systems and computing devices then associate a detection probability and a false negative rate with the failed corrective action to create additional status evidence, and re-rank the list of potential failure modes for subsequent performance based on the additional status evidence.

    Abstract: A principle for handling system failure situations thereby maintaining minimum fault recovery time and providing high system availability is described, especially for controlling the system behavior in fault situations of Electronic Control Units used in automotive vehicles. This principle is providing unique solutions for fault analysis, fault recovery definition and system re-vitalization. It is a key attribute of the principle keeping the demand for hardware and software overhead at a minimum. The method applies graceful degradation of system functionality, allowing to achieve the implementation of cost effective systems.
